A trucker, a farmer, and an entrepreneur walk into a global supply shock

March 17, 2026

Key Takeaways Copied to clipboard!

  • The U.S.-Israel war with Iran is causing an economic supply shock, primarily through increased fossil fuel costs, which immediately impacts sectors like transportation and agriculture. 
  • Rising diesel prices directly increase costs for truckers, potentially leading to higher consumer prices if the burden shifts downstream, while high fertilizer costs squeeze corn farmers who have few immediate alternatives. 
  • The economic shock creates opportunities for businesses offering alternatives to oil-derived products, such as materials made from waste, as the relative cost-competitiveness of these substitutes improves. 

Segments

Defining the Supply Shock

  • Key Takeaway: The conflict in the Middle East is causing a supply shock by making fossil fuels, which are inputs for many goods, suddenly more expensive.
  • Summary: Higher gas prices and delayed international flights are symptoms of a supply shock caused by the U.S.-Israel war with Iran. Fossil fuels, which power factories, ships, and planes, have become significantly more expensive. This price increase affects inputs for numerous products, including plastics, fertilizer, and medicines.
Trucker’s Rising Fuel Costs

  • Key Takeaway: Diesel prices rose about one-third in the first month of the conflict, forcing employers to potentially restrict where company drivers can refuel to manage costs.
  • Summary: For long-haul truckers like Forrest Atkinson, the most visible effect is the sharp increase in diesel costs, which were up about 30% compared to a month prior to the war. While her employer currently covers the fuel tab, extreme price hikes could lead to company restrictions on refueling locations. Unpredictability in freight patterns, tariffs, and fuel prices makes owner-operator roles particularly risky currently.
Fertilizer Price Squeeze

(00:03:50)
  • Key Takeaway: Global natural gas market disruptions, stemming from the Persian Gulf, are driving up nitrogen fertilizer costs, which is the single biggest expense for corn farmers like Mark Mueller.
  • Summary: Nitrogen fertilizer production relies heavily on natural gas, and disruptions in the Persian Gulf, which supplies 20% of the world’s LNG, are pushing up domestic fertilizer prices. Because fertilizer is traded globally, increased demand from countries like Brazil or India can inflate North American prices, leaving farmers like Mark Mueller captive buyers just before planting season. Consolidation in the fertilizer industry, down to just four major companies, exacerbates concerns over high prices.
Plastic Alternative Competitiveness

(00:06:34)
  • Key Takeaway: The spike in oil prices, which directly increases the cost of polyethylene plastic by about 30%, significantly improves the economic competitiveness of oil-free alternatives.
  • Summary: Since most plastic is derived from oil, the cost of polyethylene, the main plastic used, increased by roughly 30% early in the conflict. UBQ Materials, which creates a plastic alternative from waste like chicken bones and mixed recyclables, becomes more economically attractive when traditional plastic prices rise. This substitution effect is a key way the economy can adapt to sustained oil price increases over time.
Short-Term Adaptation Limits

(00:08:27)
  • Key Takeaway: While ingenuity drives long-term substitution, businesses face limited short-term options against sustained energy price hikes, often resulting in minor adjustments or potential bankruptcy.
  • Summary: Short-term adjustments for businesses are minimal, such as a trucker avoiding the most expensive gas stations or a farmer switching crops. If the war persists, the economy will change as businesses that cannot absorb higher energy costs may fail, being replaced by firms better prepared for the new price environment. Human ingenuity remains a factor in predicting the ultimate economic impact of the oil crisis.
